To connect, you must check for the IP address assigned to your iOS device:
Just tap Settings > Wi-Fi and select the Wi-Fi network's details.

This is an OpenVPN client for jail broken iOS devices. It is great for remote file/network
access and secure web browsing when using Wi-Fi hotspots. It's a GUI-based
port of the OpenVPN command-line client with a tunemu patch.

The connection settings must be defined in an OpenVPN configuration file (.conf or .ovpn), just like the PC version of the OpenVPN client. Within the app you can download config files for third-party VPN providers.

You can import custom settings by packaging your OpenVPN configuration file and any certificates into a ZIP file using your PC. Then you can upload it to GuizmOVPN via Wi-Fi with the app's built-in web interface, or you can upload to a web server on the Internet and download within GuizmOVPN.
